Answers

Step-by-step explanation:

I think the answer should be C

Answer: A

(2, -4) and (0,4);

x, y x, y

A. y = -4x +4; substitute the pairs

(2,-4)

-4 = -4(2) + 4 = -4; -4 = -4

(0,4)

4 = -4(0) + 4 = 4; 4 = 4

B. y = -4x - 4

(2, -4)

-4 = -4(2) - 4 = -12; -12 ≠ -4

(0,4)

4 = -4(0) - 4 = -4; -4 ≠ 4

C. y = 4x - 4

(2, -4)

-4 = 4(2) - 4 = 4; 4 ≠ -4

(0,4)

4 = 4(0) - 4 = -4; -4 ≠ 4

D. y = 4x + 4

(2, -4)

-4 = 4(2) + 4 = 12; 12 ≠ -4

(0,4)

4 = 4(0) + 4 = 4; 4 = 4

Answer A works out for both ordered pairs.

Answers

the division problem is 7 divided by 15. this can be written as 7/15. to do this, you first know that 15 doesn't go into 7, so you add a decimal point, and make the 7 70. 15 goes into 70 4 times. 15 times 4 is 60. 70-60 is 10. 15 doesn't go into 10, so you add another 0 and bring it down. 15 goes into 100 6 times. 15 times 6 is 90. 100-90 is 10. 15 doesn't go into 10, so you bring down another 0. 15 goes into 100 6 times. 15 times 6 is 90. 100-90 is 10. at this point, you can probably guess that the 6 will go on for a while. this means it is repeating. this means your answer is "a".

Enter your answer in the box.

Answers

Answer:

18 units cubed. (18units³) also, replace 'units' with whatever units you were given (cm, inches, etc.)

Step-by-step explanation:

(the answer below is assuming each cube has a length of one unit. If they have a different length, then multiply the final answer by the length squared) (answer x length x length)

answer: there are six rows of cubes with 3 cubes in each row each. Each cube is 1x1, so 6 x 3 x 1 x 1 = 18. (with units): 18units³

also, replace 'units' with whatever units you were given (cm, inches, etc.)

Answers

Answer:

Exponential decay. Your growth factor is 1/8, which is between 0 and 1. Thus, the value is decreasing exponentially.

If the growth factor is greater than 1, you have exponential growth. Logarithmic functions will always contain a logarithm, so you can quickly rule out those options.

Equations contain an equal sign, but expressions only contain numbers and variables.

The expression in option A) is not an expression as it is a equation.

What are linear equations?

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here, option A as 3x+4=7 thus it is an linear equation but an expression is a polynomial where there are no signs such as<,>=

Hence, Option A is the correct answer.

1. Each side of cube 1 is 3 feet x 3 feet, so each side has an area of 9 square feet. Multiply by 6 sides and the area is 54 square feet.

2. Each side is 2 feet x 2 feet so the area of one side is 4 square feet. Multiply by 6 sides and the area is 24 square feet.

3. 54 + 24 = 78 square feet
